Super L-Band DWDM EDFA

As the growing demand of data transmission capacity, Amonics’ Super L-band (L++ band) DWDM Erbium-doped Fiber Amplifier (EDFA) is the ideal solution that features Super L-band operating range up to 1626.2nm. The EDFA adopts the design of high-power pump laser and high-stability pump combiners, renowned for robustness in high power boosting. It provides flattened gain across the operating wavelength range and very low noise figure.

The turnkey microprocessor-controlled EDFAs provide illustrative alarms and status indicators. An integrated RS232 computer interface enables easy control, diagnostic functions and data acquisition.
